Hi there, I am new here. I have a 425 nailhead out of a 64 wildcat and it's been put into a 56 chevy 2 door wagon with a 700r4. the radiator is a stock 56 chevy rad. I am trying to do a cooling system flush but am having a hard time locating the drain plugs on the engine block. I understand there is one plug on each side of block but looking online can't seem to find any photos or specific details on where these drain plugs are. Does anyone have pictures or a manual which can give me a better idea? Thanks!
On passenger side, look next to the dip stick tube casting, it is a 1/8 NPT plug below the head. On driver's side, between number 4 and 6 (closer to 6).
